HI @csolisr ,
@ljf draw my attention to your post
(Sorry, in French… most of the time my posts are in English! (Serveur de live streaming sur nginx+rtmp. Expérience ? Avec YNH?)
I am looking gor an open source and simple live streaming solution. What you mention seems to be interesting.
In fact, I was looking a solution based on RTMP protocle.
Regarding you question about this application on Debian, let me share this answer from @Aleks (my humble translation from French into English)
the nginx module which has to be installed is not available in the Stretch distribution. although it is available in the tretch-backports : Debian -- Error .
It is necessary to install the stretch-backports on the server ( a new hack = one more risk but it should be OK).
Let me share your post in my (French-speaking) communauté 
Have a fun time and take care
See you, José from France.
